Lawn Mower Tune Up - Keep Your Mower in Good Shape With These Simple Steps
When you’re finishing your mowing job after end of season, mostly you’ll just shove your mower into the corner, where it sits right now.
It may seem like a good idea at that time but there are things you should do before put your mower into bed, if you want to swing into coming season without headache from starter failure.
Below is the detailed instruction on how to tune up your lawn mower by yourself:
- Before doing the tune-up, the engine needs to be warmed up. Put enough gas in the tank to keep the lawn mower running. Start the engine and allow it to run until the machine runs out of gas. At last, you are now ready to start the tune-up process.
- As a safety precaution, the spark plug wire must be disconnected to prevent the engine from starting accidentally.
- Change Your Oil. Purchase the correct type of oil, you can check the owner’s manual for reference. See our instructions on how to change the oil.
- Change Spark Plug
- Replace air filter
How to change the oil
- Wipe off any dirt surrounding the upper part where the machine will be filled with oil. Using an old toothbrush will be useful in this task.
- If your oil tank has dipstick, unscrew and remove it.
- A plug is situated on the underside of the machine and on the lower side of the oil tank. Unscrew this plug to drain the old oil.
- Support the machine by using blocks, allowing a tilt to provide you an access to the plug.
- Place a container to catch the oil under the plug.
- Using a socket wrench, unscrew the plug by turning in on counter clockwise direction and allow the dirty oil to spill over.
- Using the clockwise motion, screw back the drain plug back.
- Avoid over-tightening it, so that you’ll get it easily on the next schedule of your mower tune up.
- Tighten it moderately and check periodically if it has loosened because of vibrations during mowing season.
- Also, replace the oil filter if your machine has it and clean the gasket.
- Remove all the blocks to level the machine back. Using the new oil, fill the oil tank up to the correct level, while replacing the dipstick and cap.
- Refill the gas and connect again the spark plug wire.
- Start the machine, allow the engine to be idle to check for oil leaks.
